It is reported that Muḥammad [Ibn Sīrīn] – Allāh have mercy him – said:

We were once in the house of ʿAlqamah b. Qays. Rabīʿ b. Ḵuthaym entered upon us and sat in a corner of the house. Then he said, “Speak only a little except for nine things: subḥānallāh, al-ḥamdulillāh, lā ilāha illallāh, Allāhu ʾakbar, reciting the Qurān, enjoining good, forbidding wrong, asking Allāh for what is good and seeking His protection from harm (evil).”
